SharePoint 2010 - How to remove event receiver off content type?

Question

Is there a set way in code to remove event receivers off of content types? I have some legacy content types that have event receivers that are erroring out and I would like to delete them off the content type if possible. I don't know if there is a specific step or if this is even possible. I know I can go and kill them at the list level but they are still registered on the content type. I imagine that once I delete them from the list that everything should be fine but again, not sure and wanted others to weigh in on this if they have had to do the same thing.
